The fertilizer application schedule is shown in table 2: and (3) setting 4 treatments according to the test results of the early-stage fertilizers of the subject group and the fertilizing amount in different growth periods, wherein each treatment is subjected to decrement treatment according to the nitrogen fertilizer content.
TABLE 2 greenhouse controlled release fertilizer application protocol for Notoginseng radix
T1: equivalently treating the controlled release fertilizer;
t2: 85% controlled release fertilizer;
t3: 75% of controlled release fertilizer;
t4: 50% controlled release fertilizer;
positive CK: common compound fertilizer for field management (30:10: 10): spraying (5kg compound fertilizer and 100 liters of water) per mu;
negative CK: water soluble fertilizer and foliage fertilizer.
Each treatment is arranged in 4 fields, 3 repetitions/field, for a total of 12 repetitions/treatment.
Field layout (as shown): cell area: 1.5m x4 m-6 m 2.
Since the growth of panax notoginseng is affected by temperature and light, a random arrangement is adopted.
Taking soil samples from each treatment district according to a five-point method, wherein the number of the samples is 5-10, the soil samples with the depth of 0-10 cm are taken from each sampling point, and 500g of the soil samples are filled into a sterile self-sealing bag. Grinding, mixing and sieving each bag of soil sample (60-mesh sieve), and mixing and analyzing the same treated plot soil samples in the same row.
The plant sampling method comprises the following steps: (1) removing the plant at the border of the cell; (2) sampling was carried out by a three-point sampling method, 10 strains/point.
Example 1 measurement of soil chemical Properties [1,2]
(1) The pH value of the soil is as follows: weighing 10g air-dried soil sample, dissolving in 50ml solution to remove CO2Shaking in a shaking table at 20-25 deg.C for 30min (shaking machine speed 150-180 times per minute), taking out, filtering in 50ml beaker, and measuring with inoLab pH740 pH meter;
(2) the content of alkaline hydrolysis nitrogen in soil: alkaline hydrolysis diffusion method;
(3) soil quick-acting phosphorus: 0.05mol/L HCl-0.025 mol/L (1/2H)2SO4) A method;
(4) soil quick-acting potassium: flame photometry;
(5) and (3) measuring the organic matters of the soil: volumetric method of potassium dichromate.
TABLE 3 Standard soil environmental conditions suitable for growth of Panax Notoginseng [3,4]
The test results show that:
pH: the differences between treatments were not significant. The pH showed an overall rising trend with decreasing application rate of the controlled release fertilizer compared to conventional fertilization (positive CK) and no fertilizer (negative CK).
Conductivity: the difference between the conventional compound fertilizer treatment and the controlled release fertilizer treatment is not obvious. Wherein the highest soil conductivity of 15 percent (T2) of the controlled release fertilizer nitrogen fertilizer application reduction is 500.00 mu s/cm; the conductivity of the soil without fertilization treatment was the lowest at 435.50. mu.s/cm. In addition to the T2 treatment, the controlled release fertilizer treatment decreased the soil conductivity as the amount of fertilizer applied decreased. The result shows that the fertilization can increase the conductivity value of the soil, and the more the controlled release fertilizer is applied in a certain range, the higher the conductivity of the soil is.
Organic matter: the application of the controlled release fertilizer can increase the content of organic matters in soil, but has no significant difference from the conventional fertilizer application (positive CK). When the controlled release fertilizer nitrogen fertilizer is applied in equal amount (T1), the content of organic matters in soil is the highest, namely 55.05 g/kg. With the reduction of nitrogen fertilizer, the organic matter content of T2, T3 and T4 is reduced to 52.13, 53.83 and 52.45g/kg respectively; are all higher than 51.49g/kg in conventional treatment (Yang CK).
TABLE 4 influence of different fertilization treatments on the physicochemical properties of the soil for planting Panax notoginseng
Organic matter: the application of the controlled release fertilizer can increase the content of alkaline hydrolysis nitrogen in soil. Compared with the conventional fertilization (152.55mg/kg), the controlled release fertilizer nitrogen fertilizer application reduction by 15 percent (T2) and 50 percent (T4) can obviously increase the organic matter content in the soil, and the organic matter content is 176.71 mg/kg and 163.95mg/kg respectively.
Available phosphorus: the differences between treatments were not significant. Wherein, when the controlled release fertilizer nitrogen fertilizer is applied in equal amount (T1), the content of available phosphorus in the soil is the highest and is 15.82 mg/kg.
Quick-acting potassium: with the reduction of the application amount of the controlled release fertilizer, the content of the quick-acting potassium in the soil shows an increasing trend, namely 400.53, 407.37, 405.78 and 409.43mg/kg respectively, and the difference among the treatments is not obvious; but are lower than the conventional fertilizer application (424.06mg/kg) and higher than the non-fertilizer application (negative CK, 385.67 mg/kg).
The invention and its embodiments have been described above, without limitation, and what is shown in the drawings is only one of the embodiments of the invention, to which the actual structure is not limited. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
